## Abstract DNA polymerase activity was measured in mouse embryos at stages before implantation to determine whether it increases in proportion to the amount of DNA synthesis, as it does in populations of differentiated mammalian cells, or remains constant, as it does in early sea urchin embryos. T

## Abstract DNA polymerase activity with Poly (A)Β·oligo(dT) as a templateβprimer has been found in preimplantation mouse embryos. A sharp increase in enzyme activity was observed at the time of formation of inner cell mass (ICM) and trophoblast cells. Differential inhibition of enzyme activity befo
## Abstract Cell division stops in mouse blastocysts during the prolonged, freeβliving phase associated with delayed implantation. It is not known how the embryos are rendered mitotically dormant and then reactivated to implant at a later time, and the present experiments were undertaken to determi
